2` Claims.' (C1. is-188) This inventionrelates to a dyeing machine fordyeing wool, rayon, cotton and the like, the general 'object of theinvention being to keep the material immerseddn the `dyeing liquid atall times, thus insuring'a `uniform color and penetration to all partsof material by the dyeing liquid. lAnother object of the invention is toprovide means for supporting the material in loops in the machine'withmeans for slowly turning the loops at4 intervals and in oppositedirections.

. Another object of the invention is to provide means'for adjusting thelower supporting means of; the loops to suit the` length of the loops.

'Ihisinvention also consists in certainy other features of constructionand in the combination and .arrangement of the severalparts to behereinafterfully described, `illustrated in the accom` panying drawingsand specically pointed out inthe appended claims. o l, 4 -I`n.describing the invention in detail, reference will behad to theaccompanying drawings where-` inilike` characters denote like` orcorresponding parts throughout the several views,- and in which: Figure1 is an elevation of the invention show-` ing'theframe raised from `thetank.

In these drawings the letter A indicates the www@ ,11S provided .with aShort` #QP Piece at one end thereof and a vertically arranged`transversely extending partition member 2 extending across said endportionof the tank and a horizontal plate 3 `covers the top of the spaceformed by the partition member 2 andthe adjacent end wall of the tank.This plate 3 is formed with a large circular openingv 5v in itsl centerand a plurality of holes 6' are arranged in the plate between the centerhole or opening and each end of the plate. A shaft 6 passes verticallythrough the top piece I and is journaled inthe o bottom of the tank asshown at 'I and a sleeve 8 is fastened to the shaft and carries apropeller 9 which is located ingthe lower part of the `space formed bythe partition member 2 and the adjacent end walls of the tank. A motor Mis fas'- tened to the. top piece I and gears 9 connect the motor shaftwith the `upper, end of theshaft 6 Thus the dyeing liquid placed in thetank willlbe i agitated and `caused to-circulate and this liquid isheated by steamintroduced into the pipes I which have horizontal partsII in the bottom of the tank which are provided with perforations I2.

A frame Bis adapted to be placed in the tank through the open topthereof` and to be removed therefrom by means of a suitable hoist to beconnected to the stays I3 connectedv to the stationary parts of` a`cover C,V these `stationary parts being connected by uprights I4 tothetop of the frame B. The cover C is `provided with the hinged doors vIwhich carry` the eyebolts I6 which are to receive bars for holding theframe from shifting while in the tank.

The Aframe B includes the four corner posts I'I,

the two posts -at one side of the frame being connected together by aside beam I8 and the other two posts being connected together bya sidebeam I9. The inner face ofthe beam I8 has a pluralityof verticallyarrangedslots ory grooves therein opening out through the upper edge ofthe beam and terminating at their lower ends in circular recesses 2l,see Figure 8. grooves land recesses are to receive the roundedreducedends 22 of bars 23 of square shape in cross section, the otherendlof each bar having a reduced part 24 whichis of square shape incross section. `The beam 1I91carries a plurality of rotary bushings 25,one of which is arranged opposite each recess 2 Iwand the inner end ofeach bushing has a square recess 26` therein for receiving the squareend'24. `The .outer end of each bushing has a shank 2'I extendingtherefromof non-circular shape in cross section which receives the pairof collars 28 between which is placed the toothedwheel 29, the parts 28'and 29 being held These tightening the chains 49.

on the shank by a nut 30 .as more clearly shown in Figure 12. A shaft 3|is journaled in one of the posts'which supports the beam I9 and carriesa pair of sprockets 32 and a small sprocket 33, a chain 34 passing overthe small sprocket and over a sprocket 35 on a shaft 35 rotatablysupported on a part of the cover C. A shaft 36 is carried by the slidingblock 31 at the other end of the row of wheels 29 and this block can beadjusted by means of a set screw 38. A pair of sprockets 39 is fastenedto the shaft 36 :and a` pair of endless chains 40 pass over thesprockets 32 and 39. Portions of the two chains 40 are connectedtogether by the bars 4I for engaging certain teeth of the wheels 29 sothat each time a'bar 4I strikes a tooth the Wheel will be' partly turnedand, of course, this motion will be imparted to the bar 23 to which thewheel is attached. By only providing a few of the bars 4I l the squarebars 23 will only be partly rotated at infrequent intervals and bymaking the drive for shaft 35 `a reversible one the chains will causethe square bars 23 to be rotated or partly so rst in one direction andthen in the other. Of course, the block 31 and the screw 38 providemeans for Lower side beams 42 areislidably arranged on the posts I1 andone beam has recesses 43 in its inner face While the other beam hastransverse holes 44 passing therethrough. Round rods 45 are adapted tobe passed through the holes with one end of each rod engaging a recess43 and the other end fitting in a hole 44. After the rods 45 are put inplace a bar 46, slidably supported on the outer face of the beam 42which has the holes 44 therein is moved to place the holes 41 thereinout of register with the holes 44. Of course, when the rods 4.5 are tobe putin place or removed the sliding bar 46 is adjusted to place itsholes 41 in registry with the holes 44.' As shown .in Figure 5, thissliding bar 46 slides through the guides 48 carried by the beam 42 andit is held in the position shown in Figure 5 by the clamping device l49.Each beam 42 can be slidably connected `with the posts I1 in anysuitable manner though I prefer to form notches in the inner portions ofthe beams 42. through which the posts I1 pass and then plates 42' arefastened to the inner faces of the beams 42 to cover the notches so asto slidingly hold the beams to the posts.

Each beam 42 can be adjusted vertically on its posts I1 by means of theyhandle lever 50 pivoted to one post by a p`in 5I which may be placed inany one of a row of holes 52. Diverging links 52 are pivotally connectedat their upper ends to an vintermediate' part of the lever and havetheir lower-ends pivoted toa beam 42 as shown at 53. Each lever is heldin adjusted position through means ofan arcuate bar 54 depending from apart'of the upper portion of the frame vand having an arcuatelongitudinally extending slot 55 therein, the side walls of which arenotched as shown at 56 and a latch button 51 is carried by a handle part58 rotatably arranged in the lever 50. Thus by turning the part 58 thelatch button can be removed fro-m a' pair of the notches 56 and thelever adjusted upwardly and downwardly and the latch button placed inanother pair of notches as shown more clearly in Figure 1'0. As showninlFigures 10 and l1 the latch button includes a rectangular part whichhas a sliding t in a pair of the notches 56 and a circular part which isconnected with a nut 58" on a threaded part of the shank of the part 58.

Thus by turning the member 58' in an anticlockwise direction the nut 58"will be fed toward the end of the threaded part carrying the button 51with itv until the rectangular part of the button passes out of thespace formed by a pair of the notches 56. Then the parts can be adjustedto another pair of notches and the member 5B' is turned in a clockwisedirection which will cause the nut and button 51 to move inwardly toplace the button or the rectangular part thereof in said other pair ofnotches.

Brackets 59 are carried by the posts adjacent the under parts of thebeams I8 and I9 and these brackets support the rods 58 and brackets 59extend upwardly yand inwardly from the beams 4.2 and support the rods60. The rods 58 and 60 prevent spreading movement of the Ayarn supportedon the members 23 and 45, as shown in dotted lines at 6I in Figure 3.

It will be seen that the square bars can be raised at their ends whichengage the grooves 26 and recesses 2|, after the frame has been liftedtothe position shown in Figure 1 and the loopslof yarn placed over themso that'the loops will be suspended from these bars 23. Then theV roundbars 45 are moved outwardly through the holes 44 after the bar 46 hasbeen adjusted to v place its holes in registry with the holes 44 andthen these bars 45 are replaced and passed through the lower ends of theloops of yarn after which the bar 46 is moved to the position shown inFigure 5 and locked in position by the clamping device 49. Then thelever 50 is adjusted to cause the bars orrods 45 to properly engage thelower ends of the loops. ered into the tank, the motor M started toagitate and circulate the dyeing liquid in the `tank and the shaft 35 isstarted to operate the chains 40, the upper reaches of which ride overthe collars 28 and every time a rod 4I strikes a tooth vof a wheel, saidwheel will be partly rotated and this movement willbe imparted to therod 23, the square end of which is placed in the square recess 26 of thebushing 25 being so moved. Thus. the loops of yarn are partly revolvedat intervalsA 'Ihen the frame is lowi andas before stated by reversingthe shaft 35' l this partial revolving motion can be reversed.

Uprights 63 extend upwardly from the top of the tank'for supporting thecover member C in position shown in Figure 2 and an upright '64 extendsupwardly from the top of the tank and carries` a stub shaft 61 having atongue on its inner end for engaging a groove 68 in the shaft 35 whenthe frame B is in lowered position. A

pulley or gear 69 is fastened to the shaft 61 and is suitably connectedto a reversible motor, not shown. A removable bar is arranged at one endof the bottom of the frame, Ysaid bar being provided with -a latch 66 ateach end thereof -for holding it in position and by removing the'barloading or unloading of the frame is facilitated. It is thought from theforegoing description that the advantages and novel features of theinvention will be readily apparent.

It is to be understood that changes may bey made in the construction andin the combination and arrangement .of the several parts pro-` videdthat such changes fall within the scope of the appended claims.
